Background of the issue:
I'm trying to translate my checkout page on my site hidden link using WPML. In the string translations tab, the Bulgarian strings are set inside the English and can't be edited. It only lets me translate the Bulgarian string, but I need to translate from Bulgarian to English.Also the troubleshooting page is not working correctly.
Symptoms:
On the checkout page, the content appears in English for a couple of seconds and then changes to Bulgarian when I open the English part of the website.
Questions:
How can I edit the Bulgarian strings that are set inside the English in the string translations tab?
Why does the content on the checkout page change from English to Bulgarian after a few seconds?
